  • Silver and titanium dioxide based optically transparent antimicrobial coatings and related methods
    Patent number: 11951221
    Abstract: Methods of reducing microbial attachment to a surface are provided, including methods comprising illuminating a surface comprising a substrate and a coating on the substrate with ultraviolet light, wherein the coating comprises anatase titanium dioxide nanoparticles functionalized with silver nanoparticles and is optically transparent to visible light; and exposing the illuminated surface to microbes. The coating exhibits a reduction in microbial attachment as compared to the coating absent the illumination.
    Type: Grant
